  • Swapping brush for brushless

    Greetings All,
    I have a 3.5" Skipjack WTC and want to drop in a brushless motor and ESC. I was wondering if anyone has done this before and has any pointers or knows of any motors of the right dimensions that easily drop in with the old hardware and as little modification as possible. Thanks,
    Sean
    Ya know, I quite like sinking skimmers!

    Sean,


    The orange motors I offer would be a great fit for that cylinder. Add a BLHeli ESC and a 3A BEC and you've got your setup.
    Two ways to mount: inside or outside. The motors of this kV rating are all outrunners (the outside of the motor spins). You have to mount it via a mounting plate on the rear of the motor.

    For inside mounting, you'll need to fabricate a mounting plate that ties into the rear motor bulkhead. Make four standoff studs and mount a plate to those.
    For outside mounting (yes you can run these in the wet all day long with no adverse effects), simply bolt it to your endcap and mount some bullet connectors in the bulkhead for power.

      Not to threadjack but can you run them wet in Salt water?

        The little research that I've done says that brushless will work well in salt water. People recommend coating with silicone oil and washing out thoroughly with soapy water after every run. Motor life will be reduced (drastically reduced?), but they'll work well for, say, a season of running or maybe two before you'll want to replace the motor. Fortunately, replacement is quick, easy and cheap.
